Published Studies Related to Videx (Didanosine)
Four year follow-up of simplification therapy with once-daily emtricitabine, didanosine and efavirenz in HIV-infected patients (ALIZE ANRS 099 trial). [2011.01]
BACKGROUND: once-daily combinations of efavirenz and two nucleoside analogues are recommended for the treatment of HIV infection. Long-term efficacy and safety data are scarce for the combination of efavirenz, emtricitabine and didanosine... CONCLUSIONS: a once-daily regimen of emtricitabine, didanosine and efavirenz provided a durable antiretroviral response and was well tolerated through 4 years of therapy.
Response to zidovudine/didanosine-containing combination antiretroviral therapy among HIV-1 subtype C-infected adults in Botswana: two-year outcomes from a randomized clinical trial. [2009.05.01]
BACKGROUND: Numerous national antiretroviral (ARV) treatment initiatives offering protease inhibitor-sparing combination antiretroviral therapy (cART) have recently commenced in southern Africa, the first of which began in Botswana in January 2002. Evaluation of the efficacy and tolerability of various protease inhibitor-sparing cART regimens requires intensive study in the region, as does investigation of the development of drug resistance and the optimal means of sustaining adherence. The "Tshepo" Study is the first large-scale, randomized, clinical trial that addresses these important issues among HIV-1 subtype C-infected ARV treatment-naive adults in southern Africa... CONCLUSIONS: The preliminary study results show overall excellent efficacy and tolerability of NNRTI-based cART among HIV-1 subtype C-infected adults. ZDV/ddI-containing cART, however, is inferior to the dual NRTIs d4T/3TC or ZDV/3TC when used with an NNRTI for first-line cART.
Didanosine, lamivudine, and efavirenz versus zidovudine, lamivudine, and efavirenz for the initial treatment of HIV type 1 infection: final analysis (48 weeks) of a prospective, randomized, noninferiority clinical trial, GESIDA 3903. [2008.10.15]
BACKGROUND: The combination of didanosine, lamivudine, and efavirenz (ddI/3TC/EFV) for the initial treatment of human immunodeficiency virus type 1 (HIV-1) infection has been insufficiently analyzed in clinical trials... CONCLUSIONS: At week 48, ddI/3TC/EFV administered once per day with food did not have results inferior to those of COM/EFV treatment. A statistically significantly higher proportion of patients in the COM/EFV arm than in the ddI/3TC/EFV arm discontinued therapy because of adverse events, mainly because of hematological toxicity. CLINICAL TRIALS REGISTRATION: NCT00256828.
Low-level K65R mutation in HIV-1 reverse transcriptase of treatment-experienced patients exposed to abacavir or didanosine. [2007.10.01]
BACKGROUND: Prior abacavir (ABC) or didanosine (ddI) therapy can result in the L74V/I or K65R mutation in HIV-1 reverse transcriptase. Preexisting K65R may have an impact on the treatment response to tenofovir disoproxil fumarate (TDF)... CONCLUSIONS: Prior therapy with ABC or ddI can result in a population genotype that shows K65R or L74V/I but does not reveal low-level K65R present in some patients. Subsequent treatment intensification with TDF resulted in a poor virologic response and may result in expansion of the preexisting K65R mutant.
Stavudine but not didanosine as part of HAART contributes to peripheral lipoatrophy: a substudy from the Antiretroviral Regimen Evaluation Study (ARES). [2007.09]
CONCLUSION: This study suggests that didanosine/lamivudine, when combined with either nevirapine or ritonavir-boosted saquinavir over 96 weeks of therapy, is possibly not associated with limb fat atrophy, in contrast to when treatment contained didanosine, stavudine, and nelfinavir combined.
Clinical Trials Related to Videx (Didanosine)
Bioequivalence Study of Didanosine in Children Treated for HIV [Not yet recruiting]
The purpose of this study is to show that the administration of 400/mg/m2/day of
didanosine(ddI) during the meal is bioequivalent to the administration of 240/mg/m2/day of
didanosine during fasting, in HIV infected children treated by a ARV combination including
Antiretroviral Switch From Didanosine to Tenofovir in HIV/HCV co-Infected Patients [Recruiting]
The primary purpose of this study is to evaluate the impact of changing didanosine in an
effective anti-HIV regimen to tenofovir on virologic suppression. We hypothesize that, in
patients with maximal virologic suppression on a double class regimen (including two NRTIs
and an NNRTI or a PI, boosted with RTV or not), a single drug substitution of didanosine for
tenofovir will represent a viable strategy without any negative impact on the virologic
efficacy of the regimen.
Evaluation of Three Strategies of Second-line Antiretroviral Treatment in Africa (Dakar - Bobo-Dioulasso - YaoundÃ©) [Recruiting]
Since the first line antiretroviral (ARV) treatment is now largely accessible in the
Sub-Saharian Africa countries, documentation of virological failure, drug resistance
patterns and second line treatment evaluation are still to be consolidated in settings where
viral load monitoring is not available and non-B HIV subtype is predominant.
This trial aims at evaluating the efficacy and tolerance of 3 different second line
treatment strategies: two recommended by WHO combine two non-nucleoside reverse
transcriptase inhibitor associated with a ritonavir boosted protease inhibitor
(emtricitabine-tenofovir-lopinavir/ritonavir and abacavir-didanosine-lopinavir/ritonavir);
the third strategy combines emtricitabine-tenofovir-darunavir/ritonavir and is not yet
evaluated in Sub-Saharian Africa. Darunavir has a potentially superior antiviral efficacy, a
better tolerance and its single daily administration may facilitate treatment adherence.
Safety, Tolerability and Pharmacokinetics of Efavirenz in HIV-Infected Children [Recruiting]
The primary purpose of this study is to find the dose of Efavirenz for young children. The
safety and how the medication is tolerated will also be studied.
Reducing the Incidence of Nevirapine Resistance Mutations in Pregnant HIV Infected Women Who Receive Anti-HIV Drugs Prior to and After Giving Birth [Recruiting]
The purpose of this study is to determine which of 3 different anti-HIV drug regimens given
to HIV infected pregnant women during and after their pregnancies is most effective in
reducing the incidence of nevirapine (NVP) resistance mutations. Blood levels of NVP and
lopinavir/ritonavir (LPV/r) will also be studied.
Study hypothesis: NVP resistance following single-dose NVP can be prevented with the
concomitant administration of additional antiretroviral therapy (ART).
